ABSTRACT:
A spectacle frame includes a frame body and first and second temples. Each of the temples includes fixed and extendable temple members, each of which extends longitudinally from a proximal end to a distal end and has a proximal and distal end portions. The proximal end of the fixed temple member is connected to the frame body. The extendable temple member is extendable from a normal position, where the proximal end portion of the extendable temple member is proximate to the proximal end portion of the fixed temple member and the distal end portion of the extendable temple member is proximate to the distal end portion of the fixed temple member, and an extend position, where the proximal end portion of the extendable temple member is proximate to the distal end portion of the fixed temple member and the distal end portion the extendable temple member is longitudinally spaced from the distal end portion of the fixed temple member. A biasing device provides a biasing force for urging the extendable temple member to the extended position. A latch releasably locks the extendable temple member in the normal position against the biasing force of the biasing device.
